Answer:
Agonist
Explanation:
The muscle that serves as a prime mover during a movement is called "agonist". Agonist refer to the leader muscles that contract and cause the movement.
For example, the deltoid muscle is the prime mover or agonist. Contraction of deltoid muscle causes abduction of the arm. An agonist for one type of movement may serve as antagonist or fixator for some other movement.
Explanation:
symbitotic: close ecological relationship between two or more organisms that live in close contact
mutualism is a symbiotic relationship in which both organisms benefit;
parasitism is a symbiotic relationship in which one organism benefits while the other organism is harmed
commensalism one organism benefits, the other neither benefits nor is harmed
:commensalism: answers will vary; lesser long-nosed bat/saguaro cactus; human and pet dog
Mutulism: answers will vary, human and eyelash mite, clownfish.and sea anemone
parasitism answers will vary, caterpillar and wasp, human and tapeworm
Because the outcome of the results would be much more accurate than using less people.
Skin cells, divide in a continuous manner that makes new skin cells to replace the skin cells we lost. Cells regulate their division by cyclins. Some cells divide faster when it supposed to stop dividing and this will lead to cancer disease.
<u>Explanation:</u>
The process of cell division occurs for many reasons. A single cell is divided into two which in turn they will be divided into four and so on. This corresponds to the process of cell division and cell reproduction. Cell division is an unique characteristics in human beings. Interactions between signaling proteins produces checkpoints in the cell cycle to ensure that cells do not divide at improper times.
A protein named Cyclins plays a major role in the determination and the regulation of the cell division process. The division that occurs in the cell can be regulated by the this protein type. They acts as a switch for controlling the cell division process. They will signal the cells when to divide and when to stop. When any cell continues to divided even after it is signaled to stop they may lead to a disease called cancer. These are different form the normal cells because they will be having their own growth factors that controls their growth and they will lose the normal controls on the cell cycle.
